Trademark Dispute[]

In 2015, Zimmerman attempted to register a trademark for the name Meowingtons. However, the application was rejected due to the preexisting ownership of the trademark held by an online retailer specializing in cat-themed merchandise. Because the website was founded in 2014, Zimmerman initiated a petition to challenge the existing trademark, citing his previous usage of the same name.

In 2017, Zimmerman was sued by the retailer for trademark infringement and unfair competition. The owner claimed that the business did not get its name from Zimmerman's cat. On May 15th, Zimmerman filed a countersuit against the owner with intentions to take down her domain and website.

The dispute was eventually settled in 2018.
